Boris, the first 3 should probably go into tip/x86/core, it's an ungodly tangle since it relies on the insn decoder patches in tip/x86/core, the NOP patches in tip/x86/cpu and the alternative patches in tip/x86/alternatives. Just to make life easy I'd suggest merging everything in x86/core and forgetting about the other topic branches (that's what I ended up doing locally). The remaining 13 patches depend on the first 3 as well as on the work in tip/objtool/core, just to make life more interesting still ;-) All except the last 4 patches should be fairly uncontroversial (I hope...). There's a fair number of new patches and another few have been completely rewritten, but it all seems to work nicely.
